Final answer:
Concurrent and predictive validity are sub-types of criterion-related validity, which is concerned with how well a test predicts outcomes based on another variable.
Step-by-step explanation:
Concurrent and predictive validity are sub-types of criterion-related validity. Criterion-related validity is a measure of how well one variable or set of data predicts an outcome based on another variable. Specifically, concurrent validity refers to the degree to which a test correlates with a currently existing criterion, while predictive validity assesses the effectiveness of a test in predicting a future behavior or outcome. It is important to understand that while a measurement can be reliable, consistently giving the same results under the same conditions, it is validity that assesses if the test is measuring what it is actually designed to measure.
